The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Fig. 1-5 are schematic structural diagrams of a non-ferrous metal beneficiation wastewater purification device provided in embodiments of the present application. The embodiment of the application provides a non ferrous metal ore dressing waste water clarification plant, including the coarse filtration jar 100 that connects gradually, membrane filtration jar 400 and play liquid jar 500, membrane filtration jar 400 includes: a can 410; the filter component 420, detachable sets up at the top of the jar body 410, and the lower extreme of filter component 420 stretches into the jar body 410 inside, and jar body 410 is stretched out to the upper end of filter component 420, and filter component 420 includes hollow filter part 423 and sets up the filtration membrane 4232 on filter part 423, and filter part 423 includes interior supporting layer 4231, and filtration membrane 4232 wraps up on the lateral surface of supporting layer 4231 in, and filtration membrane 4232 adopts heavy ion microporous membrane.

Illustratively, heavy ion microporous membranes, also known as nuclear pore membranes, are products that bombard a plastic film with accelerated high energy ions to form dense micropores in the plastic film. According to the types of heavy ions and the density during bombardment, the pore diameter of the micropores can be adjusted within the range of a plurality of micrometers to hundreds of micrometers, and suspended particles in the wastewater can be effectively filtered by adopting the micrometer-sized holes, so that the cleanliness of the filtered water is greatly improved.

The purification apparatus of the present application further includes a backwash water pump connected with the membrane filtration tank 400, the backwash water pump being for backwashing the filtration membrane 4232 with backwash water.

In the embodiment of the present application, the top of the can 410 is provided with an opening, on which a mounting opening 411 is provided, and the filter assembly 420 is detachably disposed in the mounting opening 411.

The mounting opening 411 has a cylindrical tubular structure, the outer diameter of which is equal to the diameter of the opening, and when the mounting opening 411 is inserted into the opening, the mounting opening 411 and the opening can be tightly connected, and then the mounting opening 411 and the opening can be stably connected together by means of welding and the like.

The filter assembly 420 and the mounting port 411 can be detachably connected in a bolt or screwed mode, when the bolt is adopted, a flange can be arranged at one contact end of the mounting port 411 and the filter assembly 420, and the connection of the two can be realized by inserting a screw rod into a screw hole of the flange. When the screwing mode is adopted, an internal thread can be arranged on the inner side surface of the mounting port 411, an external thread can be arranged on the outer side surface of the filter assembly 420, and the connection between the filter assembly 420 and the mounting port 411 can be realized by screwing the external thread into the internal thread.

In one possible embodiment, the filter assembly 420 includes an upper mounting portion 421, a lower mounting portion 422, and a filter portion 423 connected in sequence, the upper mounting portion 421 being connected to the liquid outlet tank 500 by a pipe, the lower mounting portion 422 being detachably connected to the mounting port 411.

Illustratively, when the filter assembly 420 and the mounting port 411 are connected in a screw connection manner, a boss may be disposed between the upper mounting portion 421 and the lower mounting portion 422, and the diameter of the upper mounting portion 421 is larger than that of the lower mounting portion 422, and an external thread is disposed on the outer side surface of the lower mounting portion 422, so that when the lower mounting portion 422 is rotated to the bottom in a screw connection manner, the boss of the upper mounting portion 421 may abut against the top of the mounting port 411 to achieve a limiting effect.

The upper mounting portion 421 may be detachably or integrally connected to a pipe connected to the outlet tank 500, and no matter which connection mode is adopted, it is required to ensure that the pipe is flexible over a certain length from the upper mounting portion 421, so that the filter assembly 420 can be detached from the top of the tank 410.

The filtering part 423 in the application is of a columnar hollow structure, the filtering membrane 4232 is arranged on the surface of the filtering membrane 4232, a cavity is formed in the filtering part 423, and wastewater outside the filtering part 423 passes through micropores in the filtering membrane 4232 and enters the cavity after being pressurized by equipment such as a water pump and finally is conveyed into the liquid outlet tank 500 through a pipeline.

In the embodiment of the present application, the end of the filtering part 423 remote from the lower mounting part 422 is a bottom end, and the bottom end may be a plane or a plane of other shapes. When the bottom end is a flat surface, the flat surface may be provided in a closed structure because of inconvenient installation of the filtering membrane 4232, i.e., wastewater can only enter through the filtering membrane 4232 on the side of the filtering part 423 without passing through the bottom end. After adopting planar structure, waste water can only pass through filtering membrane 4232 on the lateral surface of filtering part 423 and can enter the cavity, and the contact area between this structure and waste water is smaller, so the filtration speed is slower. In order to increase the filtering speed, the present application further provides a recess in the end of the filtering part 423 remote from the lower mounting part 422, in which a filtering membrane 4232 is also provided. The side wall of the recess is a curved surface parallel to the outer side surface of the filtering part 423, and the curved surface may have the same structure as the outer side surface, and the filtering membrane 4232 may be disposed thereon to increase the contact area with the wastewater, thereby achieving the effect of improving the filtering speed.

In one possible embodiment, the filtering part 423 includes: an outer support layer 4230 located on a side away from the axial center; an inner support layer 4231, which is located on a side closer to the axial center, wherein the inner support layer 4231 and the outer support layer 4230 are disposed opposite each other, and the filtration membrane 4232 is disposed between the outer support layer 4230 and the inner support layer 4231.

Illustratively, the outer support layer 4230 and the inner support layer 4231 are coaxial cylinders of different diameters, the outer support layer 4230 being larger in diameter than the inner support layer 4231 so that there is a gap therebetween in which the filter membrane 4232 is located. Since the filtering membrane 4232 is a soft membrane, after being installed between the inner and outer support layers, the filtering membrane 4232 may be provided with support so that the shape of the filtering membrane 4232 is maintained under water pressure.

In the embodiment of the present application, through holes are provided on both the outer support layer 4230 and the inner support layer 4231. The through holes on the outer support layer 4230 and the inner support layer 4231 may or may not be corresponding, and the through holes will not substantially affect the flow of wastewater after being provided.

Further, the filter assembly 420 in the present application may be disposable, that is, it is directly replaced after serious blockage occurs, and cleaning is not required, so the filter membrane 4232 may be set to a shape matching the shape of the gap between the outer support layer 4230 and the inner support layer 4231, that is, the filter membrane 4232 is in a circular ring structure, the multi-layer filter membrane 4232 is inserted into the gap after being sleeved with each other, and then the support layer of the filter portion 423 is connected with the bottom end or the lower mounting portion 422, so that the filter assembly 420 of the non-replaceable filter membrane 4232 can be formed.

The disposable filter assembly 420 is not required to be maintained, but has a relatively high cost, so that the filter assembly 4232 is also replaced by the disposable filter assembly, and the disposable filter assembly can be detached from the filter assembly 420 when the filter assembly 4232 is severely blocked, cleaned and then installed in the gap between the two support layers.

Specifically, the outer support layer 4230 is provided with an insertion hole 4233 extending in the axial direction. The insertion hole 4233 has a strip-shaped structure, and the length thereof is equal to the width of the filtering membrane 4232, so that one end of the filtering membrane 4232 can be inserted into the gap through the insertion hole 4233. The filter membrane 4232 will bend in the shape of the void during movement in the void, and when the length of the filter membrane 4232 is sufficiently long, it can be wound in multiple layers in the void to enhance the filtering effect on the wastewater.

Further, the number of the insertion holes 4233 may be plural, and when a plurality of insertion holes 4233 are adopted, one end of the filtering membrane 4232 may be adhered to the inner supporting layer 4231, and the other end sequentially passes through and is inserted into each insertion hole 4233, so that the filtering membrane 4232 may be tightly wound around the inner supporting layer 4231.

While preferred embodiments of the present application have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. It is therefore intended that the following claims be interpreted as including the preferred embodiments and all such alterations and modifications as fall within the scope of the application.
